Description

[Detailed Description of the Invention] This invention relates to an improvement of a mounting device for a blower that ventilates a heat exchanger housed in an air conditioner main body.

First, a conventional air conditioner will be explained. That is, in FIGS. 1 and 2, 1 is a box-shaped air conditioner main body having an inlet 2 at the bottom and an outlet 3 at the top, and 4 is a front opening 5 of the main body 1 that can be opened and closed. A front panel 6 partitions the inside of the main body 1, and a frame 9 forms a ventilation passage 7 between the inlet 2 and the outlet 3 on one side and a piping space 8 on the other side; 10 is a heat exchanger supported between the frames 6 near the suction port 3; 11 is located between the filter 9 and the heat exchanger 10 and between the frames 6; This air blower is supported by the heat exchanger 10 and blows air to the heat exchanger 10. This air blower is constructed as shown in FIG.

That is, in the figure, 12 has a bent piece 12a formed by bending the periphery, has a width almost equal to the depth of the main body 1, and is a dish-shaped mounting base that is installed between the frames 6. A rectangular through hole 13 is formed on one side in the width direction of the bottom surface 12b, and a drain pan installation portion 14, which will be described later, is formed on the other side.
15 is a fan casing, and the fan casing includes a scroll portion 16 having a width slightly shorter than the short side of the through hole 13, a throat portion 17 communicating with the scroll portion 16, the scroll portion 16, and the throat portion 17.
It has a side plate 18 that closes one side surface, that is, the back side surface of the main body 1, and a suction port 19a having a larger diameter than a motor to be described later. A blower outlet 20 is formed by the throat portion 17 and the side plates 18 and 19. Reference numeral 21 denotes a flange portion formed by bending the throat portion 17 side of the side plates 18 and 19 outward, and when the fan casing 15 is attached to the mounting base 12, the air outlet 20 of the fan casing 15 is inserted into the through hole 19a.
The mounting screws 22 are inserted into the flange portion 21 and the mounting base 12 to be fixed. 22 is a multi-blade fan housed in the fan casing 15;
A motor 4 is connected to the boss portion 23a of the fan 23 and drives the fan 23, and together with the fan 23 constitutes a blower. Reference numeral 25 denotes a three-pronged mounting foot for fixing the motor 24 to the side plate 19. 26 is installed in the installation part 14 of the mounting base 12,
This is a drain pan that receives drain from the heat exchanger 10. In the air conditioner configured in this way, indoor air is sucked in from the suction port 2 and the rear opening 1a of the main body 1, passes through the fan casing 15, and reaches the heat exchanger 10, where the cold water flowing through the heat exchanger 10 or The cool air or wind that has exchanged heat with the hot water is blown into the room from the outlet 3 for cooling or heating. However, in such an air conditioner, the fan 23 and the motor 24 are attached to the fan casing 15 as described above, and these are fixed near the through hole 13 on the bottom surface 12b of the mount, so A concentrated load is applied to the
Furthermore, since the mounting base 12 is made of a relatively thin plate, there is a drawback that the mounting base 12 may be deformed.

This invention was made to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below. That is, as shown in FIGS. 4 to 6, the side plate 19
A suction passage 27 is formed between the suction port 2 and the suction port 19a by a bent piece 19c formed by extending both sides of the portion that closes the scroll portion 16 and bending these extension portions 19b toward the front side. A drain pan 2 is formed at the upper end of the extension part 19b of the side plate 19.
A drain pan installation section 14 is formed in which the drain pan 6 is placed over the drain pan installation section 14. Moreover, by forming this drain pan installation part 14, the mounting base 12 is bent to a width slightly larger than the width of the fan casing 15, and is formed into a dish shape as in the conventional case. 13 and fan casing 15
The side plates 18 and 19 of the fan casing 15 are aligned with the air outlet 20 of the fan casing 15, and the side plates 18 and 19 of the fan casing 15 are
Insert the fan casing 15 into the mounting base 2 so that it overlaps the side plates 18 and 2a, and
9 and the bent piece 12a with mounting screws 28 inserted thereinto to assemble them integrally. Furthermore, the front end of each of the bent pieces 19c is cut out so that the size becomes larger from the upper end to the lower end. A guide (not shown) is provided along the inclined surface at the front end of the bent piece 19c, and the filter 9 is removably inserted into this guide. That is, the filter 9 is connected to the suction passage 2.
The filter 9 is detachably attached to the filtering piece 19c diagonally across the filter 7, and by removing the front panel 4, the filter 9 can be pulled out upward from the front surface through the front opening 5.
The rest of the configuration is the same as the conventional one. Therefore, in such a configuration, indoor air enters the suction passage 27 from the notch 29 through the suction port 2 and the rear opening 1a, passes through the fan casing 15 and the heat exchanger 10, and then cool or warm air is discharged from the suction port 3. Although it is blown into the room, during the flow of the indoor air sucked into the suction passage 27, the back and front sides of the drain pan 26 come into contact with the bent piece 12a of the mounting base 12 and the front panel 4 and are sealed. , is installed in the drain pan installation part 14 of the side plate 19, so that cold air or hot air does not bypass the suction passage 27, and the fan casing 1
5 and the front panel 4 can be effectively used. The fan casing 15 also has side plates 18 and 19.
and the bent piece 12a of the mounting base 12 are superimposed and that part becomes a rigid body, so that the fan casing 15,
Sufficient strength can be obtained even when the fan 23 and motor 24 are suspended.

As described above, in this invention, the side plates of the fan casing are overlapped with the inner surfaces of both side walls of the mounting base, which is formed into a dish shape by bending the periphery, and the side walls and side plates are integrally connected. It is possible to prevent the portion from becoming rigid and forming a mounting base as in the conventional case.
